Study Compares Pneumothorax Recurrence: Absorbable Mesh vs. Pleurectomy in Primary Spontaneous Pneumothorax.

\- In this group, after bullectomy or blebectomy, partially absorbable mesh (ULTRAPRO size 15 x 15 cm, Ethicon) will be prepared and inserted into the pleural cavity through one of the working ports and placed at the apical part of the thoracic cage (over the staple line) using fixation device (ProTack™ 5 mm fixation device, Medtronic).

\- In apical pleurectomy group, after bullectomy or blebectomy, the parietal surface from the apex to the fifth rib was dissected and abraded using a curved dissector with a diathermy scratch pad. Abrasion was done until a uniform aspect of bloody pleura was obtained.
